CAR-COUPLING.

`sr'EcIFIoAcIIoIv forming part of Letters Patent No. 277,300, dated Maye, 1883.

Application inea March si, 1883. (No model.)

' To all whom it may concern:

Be it known that I, JOHN C. LOOK, a citizen of the United States,residing at Yuba City, in the county of Sutter and State of California,have invented a new and useful Improvement in Gar-Couplings, of whichthe following is a specication.

My invention Vrelates to improvements in car-couplings; and it consistsin the peculiar construction and arrangement of the parts, ashereinafter more fully set forth, and pointed out in the claims. y

Figure 1 is a side elevation of my improved car-coupling. Fig. 2 is aplan view of the same. Fig. 3 is a top view of parts of two cars in theact of coupling. Fig. 4 is a similar view of two ears coupled, and Fig.5 is an elevation of one of the hand coupling links.

In the accom panyin gdrawin gs, a represents the draw-head of acar-coupling composed of .two parallel horizontal plates, a a',connected by studs c, each plate being provided with a hook, b, on eachside of it. The plates a are connected in front at their middle by aplate, a2, having a link-opening, a4. The draw-head on one car issimilar to that on the car with which it is coupled, so that adescription of one will answer for both.

d represents avertical shaft adapted to engage loosely in the opening inthe hooks b b on one side of the draw-head, and carrying a series ofparallel horizontal bars, c o. The bars c c are enlarged andproje'ctoutwardly at their front ends, and are connected together by the uprighte, passing through the enlarged parts of the bars, forming a grid, d'.By this construction the grid or series of bars c c is pivoted to thedraw-head in the aperture in the hooks l) b, on one side of it.

To one ofthe bars c', and on its outer sides, is a lug, f, to whichtheforward end of a strap, g, is pivoted, the rear end of the strapbeing pivoted to a rod, h, passing through holes in the opposite ends ofa box, ,vsecured to the frame of the car. j represents a spiral springsecured to that part ot' the rod h lying within the box, the tension ofwhich is always exerted to throw the rod forward and couple the cars.

The bar c of the grid d is provided on its inner face with a camprojection, a3, which in with a capstan, m, whereby the cars are un- Icoupled, the enlarged front portions of the bars e o engaging with thehooks b b of the op` posite draw-head when the cars are coupled, and thebars c c or grids being arranged diagonally on opposite sides of thedraw-heads on the carsto be coupled. f

The rear end of thebar c is provided with a tail end, c3, to which isconnected by a link a wing, k, pivoted on a pin, c7, in the drawhead.

As the grid composed ofthe bars c c is uncoupled by operating thecapsta-n the tail end strikes one ofthe pins c4, which acts as astoppin, the wing k turning outwardly on its pivotal pin c7, and pushingthe bars c or grid d on the draw-head of the adjacent car fromengagernent with the hooks, thus uncoupling the cars.

n represents an auxiliary spring on the front end of the rod h, betweenthe front end of the box i and a ring, o, sliding on the front end of'the rod, the function of the auxiliary spring being to operate on therod h after the bars c c on one side have been uncoupled from the hooks.

A series 0f bars, c c', forming a grid is employed to adapt the couplingof cars of' different heights.

c5 represents a stop-pin, to prevent the wing k from being thrown toofar outwardly by a lug, e6, on the wing striking against the stoppin c5.It will be seen that in this construction an ordinary link andcoupling-pins may also be employed, if desired.

p represents a grid composed of two uprights, p p', connected togetherby three parallel horizontal bars, p2.

If it is desired to couple by hand, the grids p, as vshown in Fig. 5,can be employed by passing them around the hooks of the adjacentdraw-heads and securing them in place by means ot' the pins p3, passingthrough holes in the ends of the hooks.

Having thus fully described Vmy invention, whatI claim as new, anddesire to secure by Letters Batent, is-

l. The combination, with the draw-heads a, composed of parallel platesa', provided with hooks b b and studs c4, of grids composed of a seriesof parallel horizontal bars engaging in the opposite hooks of thedraw-heads, substantially as described.

2. The combination, with draw-heads pro` vided With sidehooks, b b,ofthe grids d", placed loosely in engagement with the hooks and adaptedto have a limited longitudinal play therein, substantially as shown anddescribed.

3. The grid d', composed of the shafts or uprights d e and parallel barshaving ont- Waltllyprojecting' enlargements at one end, substantially asdescribed.

4. The draw-head a., composed of the parallel plates a', having hooks bformed in the sides of cach, the plates being connected together by theparallel studs c, and front plate, a2, having link-opening a,substantially as described.

5. The combination, With the front plate, a2, of the draw-head, of thebar c of the grid, provided with the cam projection a3, substatitiallyas described.

6. In a car-coupling, the wing 7c, pivoted in scribed.

8. The combination, with the wing k, pivoted in the draw-head andprovided with thev the auxiliary spring fn, substantially as delugvo, ofthe stop pin c5, substantially as described.

9. The combination, with the draw-head a., provided With hooks b, havingholes near their ends, ot' the hand-grids pand pins p3, substantially asdescribed.

4l0. The combination, with the draw-head a, constructed as set forth,ot`the grid [1',having the baro', provided with the cam projection a3 andtail end c, wing 7c, pivoted in the drawhead, strap g, rod h, providedwith the springs ja, capstan m, and chain l, substantially as described,and for the purpose set forth.
